To fdl wlw/)L it may concern.'

ie it known that l, CHARLES E. HECKEN- uvam'. a citizen of the UnitedStates, residing al AXnaheini, in the county of Orange and State ofCalifornia, have invented a new and useful Improvement in Internal-lCombustion Engines, of which the follow- This invention relates tointernal coni ustion engines and is particularly direct to means forsupplying moistui rand auxiliary air to the intake manif ld between thecarlbnreter and the'engine.

An object of the invention is to provide an arrangement whereby waterand auxiliary air are combined and then heated to vaporize the waterbefore being entrained into theintake manifold.

Another object is'to provide an independent means adjustable to providea minimum flow of water and means for varying the flow of auxilia aircorresponding to the speed of the engine to correspondingly vary theflow of water, combined with means normally preventing the feeding ofthe wa.- ter and auxiliary air and automatically responsive to thesuction in the manifold to permit a feeding of the water and air.

A further object is to provide a simple and efficient device for feedingand evaporating water into an air current; also to provide means fordirecting the induced moisture and air into the manifold in thedirection of fuel feedand across the path of the fuel.

Various other objects and advantages will be more fully apparent-fromthe following specification, and yby reference to the accompanvingdrawings which form a part of this disclosure and which illustrate apreferred form of embodiment of the invention.

Fig. 3 is a plan section on line 3-3- of Fig. 1.

Fig. i is an enlarged section of the discharge end of the conduit withinthe ymanifold. v

Fig. 5 is a plan view thereof.

F ig. 6 is an enlarged detail view showing one of the auxiliary airports land control valve therefor.

-In the drawings, 1 designatesfa supply conduit which conveys water froma"'sup ply tank 2 to a filtering unit designated generally by thereference numeral 3'.

The filtering unit has an'outer shell 4:v and an innerV shell 5 fo mingan outer settling'chamber 6 and an inner filtering cham` ber 7, theupper end of the two shells being joined together and closed by a cap 8screwthreaded thereon. i Secured to and depend-` ing from the cap 8 is acentral tube 9 and the inner chamber is provided with separatedperforated partitions 10 w-ith the space between the partitions filledwith ltering material 11, preferably loose wool.y Above the upperpartition l0 the inner shell 5 has a row of perforations 12 and belowsaid partition von the side opposite the inlet end of the conduit 1,-the shell 5 has two rows o f perforations l2 distributed approximatelyone-half way around the shell. In use', the larger particles of foreignmatter in the water settles to the bottom of the settling chamber 6whence it may be periodically removed through on opening' normallyclosed by a. plug 13, the water flowing through the perforation 12 tothe upper ortion of the filteng chamber 7 and throng ,es the upperperforated partitionflO;

and through the perforations 12a, is filtered i having a screw-threadengagement in Said 100 cap 8 and a -kn-urled knob 19 at its upper end sothat the valve 17 `may be manually regulated to permit a definiteminimum ow of` water from the discharge port 16.

Attached to the knob 19 is a pointer 2O 105 arranged to travel over ascale 21 on the upper surface of the cap 8 to indicate the rate of How,preferably in drops per minute.

Secured to the base of the 'filtering unit and surrounding the nozzle15, is casing 11 having a tubular member or neck 22 pro viding anauxiliary sirchamber 23 and having an outlet port 24:. y y

The member 22 has one or more air inlets or ports 25 positioned abovethe lower end of the Water nozzle 1.5, said )erts 25 being controlled bys rotary va`ve` sleeve 26- rotat-able on the member '22 and having ports27 which when in registry with the ports 25 establish communication withthe atmosphere, the ports 25 bemg closed by the solid portion of thesleeve valve 26 willen `the ports' 27 are out ofY registry with the ualopening of the ports 25 will be eiected.

The casing includes4 a drip chamber 32 carried. by the neck 22, andcommunicating iiiith e conduit 33 leading to the intake manifold 34ofthe engine and disposed in Contact with a liest radiating' portion ofthe eng1ne,.such for instance, as being coiled i around the-exhaustmanifold 35.

A suction ooeratedvnlvereomprises a needie valve meniber orplug 36lnmn'gn-lower ball end`37 reteined on the end of a valve stern 38 by nmember 39 engaging over the ball and secured o'n the end of the stem;the valve member 36 beinei allowed e slight swinging movement in tliemember 39 so as to properly align with the discharge port i6 of thewater nozzle l5, to close said port. I providev 1-means actuatedV by theengine suction, for ectuatin the Waiter valve. For this lpurpose themember 39 is rovided withVa-n annular drip plate `or ange' Il() whichhas e close sliding fit in the. lower bore of the .tubular member 22below the discharge port 16, andthe stern 38 extends through the bottomof the drip chamber 32 and is Aaxially slidable Ato open the valve 36against the tension of a normalizing spring 41.

The drip chamber 32 is provided` with drain ports 42 leadingto the borein which 'the stein 38 slides so that any water collecting in saidchamber through leakage of the valve 36, orotherwise, will graduallydrain past the valve stem 38.

The end of the conduit 33 Within the intake manifold discharges in thedirection of fue] feed (indicated by the arrow) and has a flareddischarge nozzle 43 formed with Ia. central spreading eene 4A joined to.niunication bet-Ween the auxiliary air ineens? the inner wall of thenozzle i3 arranged Webs 45 which' produce q ra-lity of diverging duetsthat spread current of air and moisture and give whirling action 'to thesainey the nosele ,733 directing said air and moisture to the 'Welle oilthe intake manifold Se across the retti of the tuel mixture. l

lli/'ith the device in normal condition with the vulve sleeve 25 inposition to close the. auxiliary air ports 25, the air l *ober is eirtight, and tbe spring el i enough to keep the Valve closed h low engines eds, no moist-nre or ensllisry air will be "ed to the intake manifold,es pecially will the suction valve be nneiiected by suction until theair tight condition in the air' chamber 23 is relieved by of tire airports 25.

lil/'lien the carburetor control means Ell operates the valve sleeve 23to open ports 25 t ie suction in the intake manifold will open the valve36 to release the Water feed7 ceriA ing the engo 4() ont of tine lowerbore of t. e member 22 to establish cwiber and drip chamber 32 to theeenden 33. The Wat-er then drips down onto titre upper face oi? the dripplate. is the drin plate is directly .in the path. o tlie :ir cnr rentthe evaporation o the Water is .fery rapidly effected. Thus, as theengine sneed increases, j a gradually increasing enior of auxiliaryairis admitted, and such ai iliary nir as it passes the water disclnnnozzle l5 entraine with it a correspondingi, increased proportion ofWater7 the air and Water in its passage through the port and around thevalve flange l0 becoming thoroughly broken up and 1ni e l,` and inflowing ,through the conduit 33 the ertreined moisture becomes vaporizedby the lient of the exhaust n'ianifolri Conso-- qucntly there isdischarged frein llie con` duit and into the intake inni'iifold a supplyof damp air varying to correspond with the speed of the engine.,Itl'vi'llbe evidentlfliat the suction increasesfdue to aniiicrense in.the sneed of the engine, the velocity ofthe auxiliary nir entering theports 25 will increase9 end es suoli nir wipes past the water dischargenozzle l5 and through the restricted dis charge port 24 it `will drawthe water from the port i6 in amounts varying to ceim 'spond with theveria-tions in the velo of the auxiliaryV nir., thereby insuring :1,cielinite ratio of nir and :veler non trolled in )'olu'xne entirely bviln relociiv of the air. Wiliile the 'form of device herein illustratedand described is Well adapted to fol fill all the objects primarilystated it not intended to confine the invention in tl lill necesa? invarious other forms all coming Within the scope of the claims whichfollow.
